The **safety helmet** is a crucial element for protecting the head in the event of an accident on two-wheeled vehicles. Its main function is to **protect the head from impacts** and distribute the force of the impact to prevent serious injuries. Additionally, the helmet helps prevent burns on the face and head when sliding on the ground after a fall.

In accident situations, it is important **not to remove the helmet** from the injured person. This is because the helmet continues to provide protection, and removing it could cause sudden movements that worsen possible injuries, especially in the neck or spine. Therefore, it is essential to keep the helmet on to avoid additional complications.

In summary, **the helmet should never be removed** from an injured person in a motorcycle accident, as its protective function is vital to minimize the risk of serious or fatal injuries.
